WIND-WHEEL.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed May 8, 1905. Serial No. 259,333-

To all whom, it may concern:

Be it known that we, MAGNUS JoHNsnN MIL- LER and J OHN BAPTISTA ZIEGLER, citizens of the United States, residing at Granger, in the county of Sweetwater and State of \Vyoming, have invented new and useful Improvements in Wind-Vvheels, of which the following is a specification.

Our invention relates to wind-wheels, and more particularly that class in which the wheel revolves in a horizontal plane.

The object of the invention is to provide improved means for governing the speed of the wheel, together with other novel features of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation of a wind-wheel constructed in accordance with our invention. Fig. 2 is a plan View. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 1. Fig. 4: is a vertical section on the line 1 4 of Fig. 2.

Referring specifically to the drawings, the tower which supports the wheel comprises a base 5, posts 6 rising therefrom and carrying at the top spaced platforms 7 and 8, respectively, between which the wheel is mounted. The lower platform 7 is supported on crossbeams 8. spanning the posts.

The blades 9 of the wheel are fast on a vertical shaft 10, which shaft is rotatably mounted in bearings in the platforms 7 and 8 and also in the base 5. A suitable gearing 11 is provided to convert and transmit the motion of the shaft 10 for the desired purpose.

The wheel-casing 12 has an opening '13, through which the wind enters to actuate the wheel. The casing is closed on top to protect the wheel from snow, rain, 620.; but it is open at the bottom to permit the wind to escape. The casing is supported on antifriction-rollers let, journaled at the outer edge of the top platform 8. The vane 15 is made fast to the casing and swings it around to keep the opening 13 squarely in line with the direction of the wind. The rollers 1 L permit the casing to be freely rotated by the vane.

At 16 is indicated a sliding door for the opening 13. The door has on top rollers 16*, which travel on a grooved track 17 on the top of the casing 12. At the bottom the door has hooks 18, extending around the bottom of the casing, whereby it is retainedv in position thereon. The door is normally held open by a spring 19, one end of which is attached to the door and its opposite end to a bracket 20, fastened to the wheel-casing. On the opposite side of the wheel-casing, at the edge of the opening 13, is a wing 21, which is connected at its outer end by a rope or cable 22 with the door. The wing 21 is mounted on the wheel-casing in the same manner as the door and extends radially from the wheelcasing at substantially right angles to the vane 15 when the door is open. The rearend ofthe door abuts against a stop 23 when it is open to prevent its being pulled around too far by the spring.

The tension of the spring is so adjusted that the door will be held open by it during ordinary wind. When the velocity of the wind increases sufficiently to overcome the tension of the spring, the wing 21 is swung around, which pulls the door over to close the opening. The area of the wing is of course less than that of the vane, so that the wheel-casing will not be swung around by the former. The extent of the swing of the wing 21 and the consequent amount of closing of the opening 13 by the door 16 is proportionate to the force of the wind, so that the speed of the wheel will be under control at all times and damage or wrecking of the machine thus avoided. When the wind goes down, the spring pulls the door open again.

The governing mechanism herein described has no complicated parts to get out of order and is thoroughly reliable and efficient in operation.

Having thus described our invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. The combination with a tower having at its top spaced platforms; of a horizontal wind-wheel mounted between the platforms; a casing inclosing the wheel, and rotatably mounted on the top platform, and having an opening to the wheel; a door controlling said opening; and a vane fixed to the casing.
